Title: Electric hand lamp
IPC: F21L14/02
Filed: 1929-05-01
Abstract: 326,083. Rademacher, E. May 1, 1029. Hand lamps without lanterns.-The body portion of an electric hand lamp consists of a handle 1, Fig. 1, made of soft rubber or similar elastic and electrically insulating material with a longitudinal bore 2 for the passage of the cable 4. One end of the handle 1 is formed with a tubular extension 3, which may be vulcanized to the cable as at 5, whilst the other end is formed with a larger bore 6, which is threaded at 7 to receive the bulb holder, and with external threads 13 to receive the sleeve-like extremity 12 of a wire guard 11 which presses a protective glass globe 9 against a jointing surface 8 on the handle 1 through the intermediary of an elastic or spring buffer 10. The guard 11 is formed with a hook 14 for hanging up the lamp. In the modification shown in Fig. 2, the tubular extension 15 is clamped tightly upon the cable 17 by means of a divided ring 19 or a wire binder or the like. The globe 23 is not flanged and is prevented from lateral displacement by a conical projection 24 on the handle 16. The screwed sleeve 25 of the guard 27 is reinforced by a flange 26 and the handle 16 is provided with a hole 35 whereby the guard can be secured against unauthorized removal by means of lead seals. The buffer 28 is spherical and engages a corresponding depression 29 in the globe 23. The bulb socket 30 may be secured to the handle 16 by means of an insulating and non-combustible threaded ring 31 and its lower part may be protected by a jacket 32 made of fireproof and insulating material and adapted to accommodate the knot 33 in the cable.

Title: Improvements relating to electrical circuit arrangements for positioning devices
Inventor: MACDONALD ALEXANDER TORRENCE
IPC: G05B19/39
Filed: 1957-04-30
Abstract: 889,382. Electric selective signalling systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 24, 1958 [April 30, 1957], No. 13792/57. Class 40(1).  In a machine tool control system the feedback loop for controlling coarse displacements includes a counter for counting pulses produced as the tool moves. As described a machine tool control system for positioning a member 3, Fig. 1, comprises two feedback loops: a coarse positioning loop including a combined multicathode gas tube counter and digital-toanalogue converter 14 which receives pulses from the stator 4 of an inductosyn 3, 4, and as a result applies an A.C. voltage analogue of the position of the member 3 to a comparing device 7 which also receives an A.C. voltage analogue of the desired coarse position of the member 3 and which, as a result, appropriately controls a motor M to move the member 3 towards the desired position, and a fine positioning loop which runs from the inductosyn stator 4 direct to an amplifier 8 by-passing the counter 14 and comparer 7. In operation a desired coarse position correct to 0.1 inch is first set up, for example on push-buttons 5 (the system being arranged so that a 360-degree change in phase of the signal from the stator 4 corresponds to a displacement of 0.1 inch) and then when this has been effected by the loop described above a desired fine position, in the form of a displacement to be added to the coarse position, is set up on push-buttons in a fine position control circuit 6 which includes a relay circuit (Fig. 2, not shown) arranged so that displacements larger than 0.03 inch are effected in two or three steps each step being no larger than 0.03 inch, and each of these displacements is effected by applying signals to a sine/cosine generator 15, as described in Specification 889,381 which is referred to, and its completion is notified to the fine control unit by the presence of a zero signal from a phase-sensitive detector 9. In the counter and digital-toanalogue converter 14 (Fig. 3, not shown) the outputs of three series-connected ten-cathode counting tubes control relays to cause appropriate secondary windings of a transformer to be series connected.

Heading E1V [Also in Divisions B3 and D1] A method of producing reinforcing elements for concrete comprises the steps of welding cross-members at intervals to longitudinal rods which are spaced parallel either singly or in groups, cutting through the crossmembers between each two or more longitudinal rods and bending the projecting ends around the rod or groups of longitudinal rods The longitudinal rods 1 are unwound on the form of cold wire from reels 3 and pass through a cold-finishing machine 4 and a straightener 5 to a lattice welding machine 6 in which the cross-members 2<SP>1</SP> are introduced. In the machine 6 they are welded by electric resistance welding to the longitudinal rods to form a lattice 7. After welding, a plurality of Gassel shears 8 cut through the cross members 2 and subsequently the projecting ends of the cross members are bent around the longitudinal rods by a bending machine 9. The resulting strip like reinforcing elements may be wound on to reelers 10 into coils or may be cut into given lengths.

An air distributer comprises a swivelling nozzle 3 universally mounted within a part spherical aperture 2 in a frame member 1. fitted to a ventilation pipe 4, the nozzle 3, provided with a central bore 5 and curved radial blades 17, 18, being adjustable in either of three operative positions, viz. a closed position, Fig. 6, in which the ends of the bore 5 are closed by the frame 1 and a pair of blades 17, 18 close the aperture 2 ; a position, Fig. 7, obtained by rotating the nozzle from the position shown in Fig. 6 through 45 degrees about the axis of the bore 5 so that two oppositely directed streams of air are distributed through the openings between the frame 1 and the nozzle 5; and a position, Fig. 8, in which jets of air flow through the bore 5 and through the openings between the frame and the curved vanes. The vanes 17, 18 are machined out of a spherical nozzle member by four cylindrical tools which are disposed at spaced angular intervals around, and at a common radius from, the centre of the bore 5, the parallel axes of the tools each being tangential to the spherical body. The frame 1 is preferably composed of two detachable parts to permit the mounting of the nozzle 5, and the spherical segment in which the nozzle swings is made of two half sections which are urged by springs against the nozzle 5. In a modification, Fig. 9, the frame member 23 carrying the nozzle threadedly engages an inner annular portion of a frame 22 round an opening in a duct 6, the frame 23 having a flange 26 to register with an annular aperture 27 in the frame 22. In an alternative arrangement the member 23 is slidably mounted in the frame 22. In another arrangement the flange 26 is formed to correspond in shape to a widened base portion of the frame 22 to act as a shutter to one, or more, orifices formed therein. In two further modifications the opening 27 in the frame either communicates with an exhaust pipe, or a fresh air supply and the nozzle 5 correspondingly communicates with a fresh air, or heated air, delivery pipe.
